{"id":"CVE-2026-83372","kind":"vulnerability","aliases":["CVE-2026-83372"],"related":[],"title":"Oracle PeopleSoft PeopleTools: Portal flaw lets low-privileged users change some data","description":"Vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: Portal).  Supported versions that are affected are 8.61-8.63. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise PeopleSoft Enterprise PeopleTools.  Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise PeopleTools, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in  unauthorized update, insert or delete access to some of PeopleSoft Enterprise PeopleTools accessible data as well as  unauthorized read access to a subset of PeopleSoft Enterprise PeopleTools accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts).  CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).","summary":"A flaw in the Portal component of Oracle PeopleSoft PeopleTools versions 8.61 to 8.63 lets an attacker with a low-privileged account over HTTP read and modify a subset of accessible data. Exploitation requires a user other than the attacker to take an action, and the CVSS scope change means it can affect other products.","severity":"medium","cvss":5.4,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["enterprise-apps","oracle","peoplesoft","peopletools","portal","vendor"],"not_affected_if":["portal-not-network-exposed","unsupported-version-outside-range"],"how_to_check":"- Check the PeopleTools version in the PeopleSoft environment; `unknown` if the sources do not say how to read it\n- Confirm whether the Portal component is exposed over HTTP to low-privileged users","fix":"- Apply the Oracle Critical Patch Update for PeopleSoft PeopleTools; the exact patch identifier is `unknown` from these sources\n- Move PeopleTools to a supported release outside `8.61-8.63` if a patch is not available","status":"open","published_at":"2026-10-20T22:19:53+00:00","first_seen_at":"2026-10-23T21:57:25+00:00","triaged_at":"2026-10-25T04:16:08+00:00","updated_at":"2026-10-25T04:16:08+00:00","category":"vendor","confidence":0.7,"triage":{"at":"2026-10-25T04:16:08Z","model":"claude-haiku-5-5","output":{"fix":"- Apply the Oracle Critical Patch Update for PeopleSoft PeopleTools; the exact patch identifier is `unknown` from these sources\n- Move PeopleTools to a supported release outside `8.61-8.63` if a patch is not available","reach":"network","title":"Oracle PeopleSoft PeopleTools: Portal flaw lets low-privileged users change some data","impact":"medium","summary":"A flaw in the Portal component of Oracle PeopleSoft PeopleTools versions 8.61 to 8.63 lets an attacker with a low-privileged account over HTTP read and modify a subset of accessible data.
